I 11,936,0@ Specification of Letters Patent. Patented Aug, 20, 1912 Application led February 27, 1911., Serial No. 610,992. i

To all whom fmag/ concern.' convolutions are inserted into'each other by 55 Be it known that I, CHARLES W. BLANEY, giving the entire spring 7 a backward twist a citizen of the United States, residing at and then screwing, as it were, the convolu- Philadelphia, in the county of Philadel- `tions into each other. I 5 phia and State of Pennsylvania., have. in- The entire spring tire 7 is secured to the vented certain new and useful Improverim 5 and maintained within the groove 6 60 ments in Vehicle-Tires, ,of which the followthereof by a metal strap `12'which extendsv ing is a specification. around the rim 5 within the spring 7 and rlhis invention relates to tires for vehicle engageswith the inner portion of the spring. This strap 12'is split as at 13, providing two end portions 14 and 15. The end portion 65V 141 is provided `with a projection 16 and the end portion 15 is provided with a projection 17. Screwed into the projectionwl is one end 18 of a connecting bolt, and screwed into the projection 17 is the other end 19 70 of the connecting bolt. The vend 18 of the connecting bolt is provided with a left-hand screw thread, and the end 19 of the connecting bolt is vprovided with a right-hand screw thread, and the central portion of the 75 connecting bolt has a nut 20 vformed thereon, whereby, by turning t-he nut 20the two ends of the bolt will draw the ends of the strap 12 toward each other in manner to firmly clamp the inner portions of the coils of the spring tire 7 within the groove 6 of Athe rim 5.

The ends o f the strap 12 are provided with outer and inner .overlapping portions 21 and 22, respectively. The inner face of 85 the inner overlapping portion 22 is engaged with the inner portionsof the coils of the spring 7, and the inner face of the outer overlapping portion 21 is engaged with the outerface of the inner overlapping portion 22; and, in addition to this, the inner overy lapping portion 22 is made tapering, whereby when the two ends of the strap 12' aredrawn toward each other by the connect-ing bolt the inner face ofthe inner overlapping portion 22 will be forced into engagement with the underlying inner .portions of the coils of the spring 7.v After the strap 12 u has been tightenedfthe connecting bolt is i secured in place, in a manner to prevent it from working loose, by suitable set screws 2% which are screwed into the projections 16 and 17 and engaged with the bolt, as shown.

In applying the tire to the wheel, the nor- Inally straight helical spring 7 is tirst bent 1'05 into' circular form, bringing its end porvtions adjacent to each other, and at the same time the strap 12 is inserted into the The object of the invention is to provide a tire of novel, simple and efficient construction formed of a helical spring. The further object of the invention is to provide a novel,

l5 simple and efficient means for securing the tire to the rim of vehicle wheel.

With this object in view, the invention consists in the novel construction and combination of parts hereinafter fully described 20 and claimed.

In the drawings :-Figure 1 is a vertical. section of my improved'tire,fon'line ll of Fig. 2, as applied to the rim of a vehicle whee. Fig. 2 is a transverse vertical sec- 25 tion of the tire on line 2 2 of Fig. 1. Fifr. 3 is a vert-ical section, on line 3-3 of Fig. 2, showing the spring tire in elevation.

t designates the felly of a vehicle wheel,

and 5 a rim secured to the periphery there- 30 of. The rim 5 is formed of metal and provided with a peripheral groove -6 therein, the rim 5 being in the form of the usual well known clencher rim lto which pneumatic tires are applied. Surrounding the rim 5 l5 and seated within the groove 6 therein is the tire 7 which is made in the form of .a helical spring.

In Figs. 1 and 8 of the drawings but short sections of the tire 7 are shown, but it will O be readily understood that the tire 7 as well as the rim 5 extends entirely around the wheel. j

The spring tire has two end portions 8 and 9 and the normal condition of the tire 5 7 is straight when it is removed from the rim 5 and when its ends 8 and 9 are disengaged from each other. When the tire 7 is applied to the rim 5 it is bent into circular form bringing its two end port-ions 8 and 9 adjacent each other, as shown in Fig. 3. The end portions 8 and 9 are attached to cach other by having the end convolution 1G of the end portion 8 inserted in the end convolutions 11 of the end portion 8. These l spring with one' end of the connecting bolt screwed a short distance into one of the projections onY the strap.

spring 7 are serewedlnto' or inserted into the end convolutions vof kthe other end portion of the spring 7, whereu on thel connecting boltl is screwed into bot projections 16 and 17 of the strap l2 to draw -the ends of the strap together and thereby clamp the tire 7 within the groove 6 of the rim 5.

It will be 'readily lunderstood that my im- `proved tiremay be ,readily attached to the ordinary welll known clencher rim now commonly used in eonnectlon with elenoher pneumatlc tires.

. Copies of this patent may beobtained for ve cents each, by addressing the Washington, D. C.

This being doraythel end convolutions of one end portion of'the'A Thus my improved.. tire l may be easily substituted or clencher pneu'- rtion of the wheels.

I claim:

The combination of a wheel rim having a peripheral "'tgroove therein, a helical spring surrounding said r1m and sea-ted in saidgroove, said spring having the convo:

lutions of one end `thereof screwed into the spaces between the convolutions of the other for retaining said end thereof, and means spring within said groove.

In testimony whereof I affix my signature in presence of two witnesses.
